6900 xt power supply needed?

[jcharnley1984]

Do know if the 6900 xt reference cards will be ok on a SF750w Corsair psu?

AMD says 850W recommended chap. So no I wouldnt run a £1000 gfx card on a £50 psu.

I use the RTX 3090 with 9900k on the same unit, does fine and former drinks more power then your GPU.

it’s not a random £50 cheap unit for those wondering, SF is platinum SFX unit and while not the pinnacle like some ATX models, does very well in reviews. Now if your have a power hungry CPU too op then sure may look at something else, but unit is no slouch. They (AMD and Nvidia) will inflate the numbers slightly to account for mediocre units too.

It depends on what cpu your running try using a psu calculator for your system spec as they tend to slightly overestimate psu usage

As £50 psu I'm not sure @Dontrocktheboat realised what psu you have which certainly ain't a £50 unit

Have you seen the price of the SF750w Corsair PSU? It's no were near £50, add another £100 and that's about right

Cost me more than my 1000w EVGA modular PSU.

On the subject, it runs my RTX 3090 fine but it's recommended spec is 750w not 850W.

6900xt - 850w psu requirements

I would say it'll be ok as it's a quality unit. I run an overclocked 10700k and a 6800XT on a RM650x np

It will be paired with a 5900x. I think I need to get a amd reference card for the full red system and constraints of the ncase m1 that will come in a couple of weeks. Worried about the size of those AIB cards in case they don’t fit. Have the cpu, psu, 980 m2 1tb. Will get the rest when I get my graphics card. Don’t think u can get more than 750w in a sff rig ??

I use 1200W or 1500W PSUs.

This makes life a lot simpler as the hardware vendors can make GPUs and CPUs with whatever TDP they wish and I never have to worry about upgrading.

People are forever making posts about futureproofing their GPU or CPU which is pointless but the one component you can futureproof is the PSU.

750W will be ample. PSU requirements are massively over egged to cater for the lowest common denominator.

I always measure the power draw from the wall under 100% load then add another couple of hundred watts extra on top.
A PSU beween 750w and 850w is probably the sweet spot unless your rocking some seriously power hungry equipment (Threadripper / SLI etc).
